Anotácia

This specification covers measurement systems used in making sound pressure level measurements in buildings in accordance with ASTM standards and guides. The measurement system includes all the components necessary to indicate measured sound pressure levels, such as microphones, preamplifiers, cables, processing units, filters, computers, display units, and other peripheral devices. Where the system is composed of components, specifications are given for microphone type and orientation, filters and windscreens. This specification does not cover systems for making sound pressure level measurements in other environments, but may include these environments in the future. Performance criteria required for measurement of sound pressure levels in building acoustics are addressed in this specification, along with the requirements for measurements systems which are not designed to conform to a normative sound level meter performance standard.
